• Engineering and Fabrication capabilities

• Process Description

A three step approach

Primary Standard

Completed,

EMRP project

Mid-scale standard

Sufficient for Small Scale LNG

Project in progress

Full scale facilities

Building traceability for LNG flow metering

5 - 25 m3/h

40 – 200 kg/min

5 – 200/400 m3/h

40 – 1600/3200 kg/min

200 - 4000 m3/h

Primary LNG mass flow standard operated and

validated in 2013 at Gasunie Peakshaver

Next Step - LNG Calibration Facility

Medium sized – Flow & Composition

Location

Rotterdam Maasvlakte, the Netherlands

Research Goals

FLOW MEASUREMENTS

1. Validating the uncertainty of flow standard

– Mass flow 40 - 1600 kg/min => Target uncertainty 0,15%*

– Volume flow 5 – 200 m3/h => Target uncertainty 0,20%*

* Requires further reducing measurement uncertainty of primary standard down to 0,10%

FLOW MEASUREMENTS

2. Investigate performance of at least two types of mass flow

and volume flow standards

– Readings as a function of flow, pressure, temperature

– Extrapolation functions (to what respect is a water calibration

representative for LNG use of a flow meter?)

– Installation effects (different flow profiles, near boiling conditions, …)

COMPOSITION MEASUREMENTS

• Validating the uncertainty of composition standard

– Cross validation with reference liquefier(s)

– Uncertainty target: 0,2% on calorific value

Design Requirements

FUNCTIONAL DESIGN REQUIREMENTS

METROLOGICAL DESIGN REQUIREMENTS

DESIGN STANDARDS

FLOW STANDARD

General

• Traceable to primary standard

• No boil-off, venting of methane to air minimized

Control parameters

• Flow Rate 5 – 200 m3/h (40 - 1600 kg/min)

Expandable to 400 m3/h

• Line pressure 1 – 10 barg(g)

• Temperature -123 to -175 °C (1 to 20 °C below boiling point)

• Composition Measurable (Mustang system), not controllable

FLOW STANDARD

Production performance

• Capacity 1 Meter under Test (MuT) per day

• Schedule of MuT 1 – 6” (expandable to 8”)

• US/DS piping 40D upstream, 8D downstream

• Calibration of two meters in series possible

• Types of MuT Coriolis, USM, Turbine, dP-type, Vortex and other

FLOW STANDARD

Metrological design rules

• LNG velocities are low to avoid flashing / bubbles.

• No double bends out of plane (swirl!), no straighteners (delta-P!)

• Temperature measurement at the position of flow meters

better than 0,1°C

• Smallest possible interconnected volumes to avoid in- and expiratory

effects during calibration time window

FLOW STANDARD

Same magnitude as gas at

atmospheric conditions!

COMPOSITION STANDARD

• Special design sampler (subcooled conditions)

• Vaporization at conditions above critical pressure

• Gas Chromatograph

• Sampling flow rate at 7,5 ml/min (LNG) / 5 l/min (gas)

• Connectable to small volume reference LNG (liquefier system NPL and/or

Effectech)

• Connectable to LNG calibration loop
